[jira] Commented: (HDFS-1477) Make NameNode Reconfigurable.

    [ https://issues.apache.org/jira/browse/HDFS-1477?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12971535#action_12971535 ] 

Jakob Homan commented on HDFS-1477:
-----------------------------------

The addInternalServlet call is used for machine-to-machine servlets that users won't use and are not authenticated (or are authenticated over kerberos).  This servlet should use the standard add call so that in a secure system the user will be authenticated.  Haven't reviewed the rest of the patch; just wanted to throw that out.
